Oh the simplicity of it all! Sadly for you chaps the real world doesn't work that way. You can't close the airline down, re-open it with fewer of the old staff in a few weeks and suddenly be profitable. The best of the old staff will already have gone somewhere else. Others will decide they don't want to rejoin the new company. What you'll be left with is a few loyalists and the unemployable, and thats no way to start up an airline. If Alitalia closes down I'd bet on it going the way of Sabena rather than Swissair.
